Drilling Rods
Mitsubishi produces both round and hexagon rods. Hexagon rods are more rigid, heavier and transfer energy more efficiently, while increasing flushing. Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications. Two different types of heat treatment are used to strengthen our percussive drill string components to maximize their performance and reliability.
- Carburization is a process used to harden the entire rod surface both internally and externally to strengthen and extend the life of the rod.
- High Frequency Induction is a process where only the thread ends of the rod are hardened to lengthen thread life
Shank Adapters
Male shank adapters are ideal for drifting, tunneling& extension applications where high bending stresses are present, and female shank adapters are used when the drilling space is limited and the total feed length is important.
Mitsubishi offers both internal and external flushing options.

Mitsubishi offers both internal and external flushing options.
- Internal flushing uses a water tube that fits through the center of the drill and into an o-ring seal in the end of the shank to transfer flushing into the drill string
- With external flushing, holes or a slot are required in the side of the shank adapter. These line up between seals inside the front head or water box of the rock drill when the shank is installed. Flushing medium is supplied directly to this device and is introduced into the drill string through the shank.
